NEW HAVEN >> AT&T is exiting the landline communications business in Connecticut and selling its UVerse and satellite television service in the state to Stamford-based Frontier Communication for $2 billion in cash.

The agreement to sell the business lines to Frontier, which was announced early Tuesday morning, keeps AT&T in the wireless business in Connecticut. Frontier officials moved quickly to reassure AT&T’s customers, telling reporters they will provide consumers the same products and services they currently enjoy, including the UVerse suite of products.

“This is a great opportunity to bring to Connecticut Frontier’s portfolio of products and services, such as Frontier Secure, our industry leading digital security offering that gives customers top-rated online computer protection and premium technical support,” Maggie Wildetrotter, Frontier’s chairwoman and chief executive officer, said in a statement. “It also allows us to introduce our local engagement management model to Connecticut in which Frontier employees provide high-quality service to their friends and neighbors and become actively involved in their communities. We see an opportunity to enhance broadband capabilities in Connecticut.”

What’s less clear is how this deal will affect AT&T’s 2,700 employees. Frontier said it expects to realize “cost synergies and savings of $200 million once the deal is complete. There was no immediate indication from Frontier as to whether some of the savings from the deal will come from layoffs.

Randall Stephenson, AT&T’s chairman and chief executive officer, said in a statement that “Frontier has proven both its ability to execute sizeable transactions and a commitment to the communications needs of urban, suburban and rural markets. Frontier has a strong track record of providing high quality service, and we look forward to them doing so in Connecticut after we close this transaction.”

The deal, which is expected to close in the second half of 2014, needs regulatory approval from U.S. Department of Justice, the Federal Communications Commission, the Connecticut Public Utilities Regulatory Authority and other state regulators.
